Thanks. Would you say it's still driveable for like 3 days? or is that taking a risk?

ya these are just wear items. Your pulleys have grease bearings. Once they wear out they squeal and squeak. The tensioner causes looseness in the belt which can also cause the high pitch noises. I drove mine for a week after the noise came before my parts arrived, no harm done.

If the pulleys seize the belt will snap and you loose cooling, power steering and can destroy your fan and rupture your expansion tank and a bunch of other things. Get it done ASAP so you don't get stranded somewhere.

Do you know the exact part number part name for that my car makes the same exact noise

you will most likely have to check and see if you have a mechanical tensioner or hydraulic tensioner. all the pulleys are above^^

RealOEM.com also will help you narrow down your model by VIN and tell you which parts you have...or you could get off the computer and open your hood and check for yourself haha

Lol I got it its mechanical. Now I'm looking at parts. The pulleys come by themselves and they Also sell them with the tensioner. Should I go for the one with the tensioner? Because that's what was said that usually makes that sound

if you want to knock out 2 birds with 1 stone then Go for it that's what I did and now my car is absolutely silent under the hood. keep in mind that belt can also cause a loud squeal like that so maybe that as well.

I asked e46mango this. If the pulleys are bad will I be able to tell just by looking at the belt while its spinning? Because the noise only happens in the morning. 4-5am then after I get off work 330pm. It's noisy for a few minutes then it stops. I looked at the belt while the car was on and it looked like it was running fine .
